Patent CA-2148146-A1 (CA)
Inventor: MCMULLIN RODERICK JOSEPH
IPC: H04B7/24
Filed: 1995-04-28
Abstract: A method and apparatus for the maintenance of Power Transmission Infrastructure is disclosed. Power Transmission Infrastructure embodies all physical elements employed directly or indirectly in the conveyance of electricity, for example, cables, conductors, insulators, tower structures, poles, grounding systems, transformers, switches, and surge arrestors.      The apparatus is inventive in that it detects events previously undetected (singularly or as a group). These include leaky arrestor, defective insulator, broken conductor, current faults, sway or galloping cables, corona, transformer degradation, structural integrity of towers and poles.      The method is inventive in that the system's data sources and data consumers communicate using a new protocol which minimizes the number of times a data element. is retransmitted. In its unrestricted form, the protocol will propagate data outward from the point of origin to the extremities of the network.     A plurality of monitor units are located at different tower structures or other structures throughout a power transmission and distribution system and each monitor unit is capable of transmitting its own identifying signal and data information collected from electromagnetic, sound, vibration, and motion sensors. The monitor units are also capable of relaying information originated by other monitor units. A remote station is provided for receiving and processing the identifying signal and data information.
Patent CA-2149603-A1 (CA)
Title: Electronic unit
Inventor: VAN GAAL ADRIANUS P
IPC: H05K7/20
Filed: 1995-05-17
Abstract: Electronic unit in which a printed circuit board is located within a housing which includes a heat sink. The board is normally urged out of heat conductive relationship with the heat sink.  As temperature increases the circuit board and heat sink are caused to move relatively so as to bring the board into heat conductive relationship with the heat sink so as to remove heat from the board.  As temperature decreases the board and heat sink are again moved out of heat conductive relationship. Preferably a heat conduction element is provided to conduct heat from the board.  This comprises at least one compressible member, e.g. compressible cellular material, which is progressively compressed as temperature increases. Preferably the heat conductive efficiency of the compressible member increases as compression increases.

Title: Chimeric selectins as simultaneous blocking agents for component selectin function
Inventor: TEDDER THOMAS F
IPC: G01N33/50
Filed: 1994-01-25
Abstract: Chimeric peptides or polypeptides that combine ligand binding portions from within the lectin and EGF domains of two different selectins are disclosed. The peptides or polypeptides can be constructed solely of the indicated portions of lectin or EGF domains or they can include portions of any of the remaining domains (SCR, transmembrane or cytoplasmic), or the entire extracellular portion, of a generic selectin molecule.

The chimeric polypeptides can be used as therapeutic agents to antagonize selectin function. They are also useful for screening for agents that are simultaneously antagonists of the function of lectin and EGF domains of different selectins.

Patent CA-2170646-A1 (CA)
Inventor: GELLEKINK BERNARD
IPC: G01S7/02
Filed: 1994-09-01
Abstract: Radar apparatus comprising a phased array antenna (1) provided with a large number of transmit and receive modules (2), a control unit (3) and a video processor (4). Per azimuth-elevation direction, the control unit (3) generates a number of pulse bursts, all of which show slight carrier frequency differences. Per pulse burst, the video processor (4) determines a doppler spectrum and compares successive spectra. As a result of the frequency differences, clutter will hardly undergo a shift, whereas targets subject to fold-back in the frequency domain will show a considerable shift. A threshold based on a mean spectrum therefor enables detect ion.

Patent CA-2176486-A1 (CA)
Inventor: WILLIAMS PHILIP MARK
IPC: H04M7/00
Filed: 1994-11-15
Abstract: In a method of controlling overloads in a telecommunications network, a module (46) for detecting and monitoring overloads is provided at a node (40). The node (40) includes a module (44) for controlling access to terminal resources such as telephones and fax machines. The module (44) also detects failed calls. Upon detecting an initial failed call to a particular called party number, a counter in module (46) is initialised. The counter is incremented for each further failed call to the particular called party number and also decremented at a fixed rate. When the number of calls in the counter rises above a first threshold, the counter goes into an overload state. When the number of calls in the counter falls below a second threshold, the counter goes into a no overload state. The module (46) sends an indication of the state of the counter and the identity of the called number to a module (48) in a node (41) which sets and updates a restriction parameter. The node (41) is upstream from the node (40) in the direction of call set up and the overload status is transmitted in the backward call set up messages. The module (49) then sets the restriction parameter in accordance with the overload status of calls to the called number and supplies this parameter to a module (49) which restricts calls to the called number. Call restriction is maintained until the overload to the called number subsides completely, The invention may also be used to detect and control calls whose call identities belong to a common set of call identities.
